W Powerskin Primo Open Back - a women's open-back competition swimsuit from the Eclipse Glare special collection.
Primo is the world's first tensoelastic competition swimsuit. It combines effective compression with exceptional stretch in a whole new way. The suit supports the muscles while allowing plenty of freedom of movement. This versatile new suit is suited to every swimming stroke and distance.
The Eclipse Glare collection draws its energizing colours from the glow of a solar eclipse. A deep blue radiating calm and determination, combined with an energetic yellow and a bold coral, channels confidence and flow into every start.
Primo is the result of several years of development and research by Arena, carried out in close cooperation with elite swimmers. The suit is not comparable to previous race suits, as it is based on an entirely new technology built on textile innovation. The word Primo means "first" in Italian.
The suit's new Hyperforce™ fabric is tensoelastic (tension + elasticity); the fabric is firm yet flexible. Primo combines the highest compression, durability and a completely new kind of stretch throughout. The suit feels pleasant to wear and does not restrict movement.
The Hyperforce™ fabric has a flow-guiding surface that reduces water resistance and improves glide. The fabric is a naturally water-repellent TPU fibre, which further improves hydrodynamics. Thanks to this material, the suit can be recycled at the end of its life.
The front of the suit features the X-tape structure familiar from Arena's Carbon Glide suit, built inside the suit. The X-shaped taping supports and stabilises the core and connects the upper body to the hips. The taping helps you notice if your body rotates too far during the stroke and returns you to an economical, streamlined swimming position.
At the back of the suit, firm taping runs over the buttocks and the backs of the thighs inside the suit. The taping lifts the hips and legs, eases leg extension and helps maintain the correct swimming position when tired. The lift can be felt especially during turns and the dolphin kick.
The stretchy suit is easy to put on, which significantly speeds up race-day routines. Primo can be put on in five minutes, whereas putting on a traditional competition swimsuit could take 30-45 minutes. Even so, choose the same size as your previous Arena competition swimsuit or follow the size chart. How quickly the suit goes on does not indicate whether the size fits. The stretchy Primo is pleasant to wear and still delivers top-class compression.
For the first time, an Arena competition swimsuit is available in two different lengths, according to torso length. The longer length is available in sizes 30-34. Added fabric on the straps improves comfort, and a silicone band at the leg opening keeps the leg in place.
